The Celtics and Los Angeles Clippers apparently turned Father’s Day into Go No Further Day, choosing to leave their stalled trade talks in the same ditch into which they were driven Saturday.In place of the discussions, questions appeared and multiplied.Is there a basis to restart the talks?

Are the Clippers looking at bigger prey?Will Doc Rivers be comfortable continuing as the Celtic coach if no escape route can be found?Has Paul Pierce hired a realtor for his Boston-area digs?The first issue that president of basketball operations Danny Ainge will likely have to tackle is finding whether things with the Clippers can be revived.According to league sources, it appears a fairly solid bet that the Celts are not going to get exactly what they wanted out of this — a couple of draft picks for Rivers; Eric Bledsoe and DeAndre Jordan for Kevin Garnett.Clearly the player transaction isn’t enough for the Clippers, who could have had the same deal back in February when it might have given them the piece they needed to make a serious run at the Western Conference title. The hope from the Celtics side has been that the club would so badly want Rivers that it balances out what it has obviously believed an unequal swap.The Clippers would certainly like to have Garnett, who, it should be reminded, would have to waive his no-trade clause. But how much are they willing to give up for a 37-year-old who is making yearly decisions on whether to retire? The Clips would have to decide how important short-term gain is to them and how easily they’d be able to transition when KG does reach his end.
